摘要: 多价电池的发展为解决目前锂离子电池安全性差、成本高及能量密度低的瓶颈提供了机会。相比于锌和镁,钙不仅储量大,而且氧化还原电势(-2.87 V)及密度更低;然而,钙金属电池相比其它多价电池得到的关注依然较少,主要原因在于非质子电解液中钙金属表面形成的钝化层无法有效传导Ca2+,进而导致相应的沉积过程难以实现;同时,稳定的储钙电极材料的研究也成为钙金属电池进一步发展的另一挑战。本文对金属钙及其合金负极在不同电解液中的电化学行为、嵌入类型(普鲁士蓝类、氧化钒等)及转换类型(钙氧电池、钙硫电池)等所涉及到的钙金属电池正极材料的研究进展进行详细综述。

Abstract: The development of multivalent batteries is promising for resolving lithium batteries' bottlenecks, such as safety issue, high cost and limited energy density. Calcium (Ca) is more abundant, and has lower standard reduction potential (-2.87 V) and density than zinc and magnesium. However, Ca-based battery gets less attention than other multivalent batteries, which is mainly due to the limitation of Ca2+ transport through the solid electrolyte interphase (passivation layer formed at the interface between Ca anode and organic electrolyte), and thus the inefficient stripping/plating processes. Meanwhile, another challenge in this field concerns the development of Ca2+-storage electrode materials and in-depth understanding of the ingress process is required. Here, we introduce recent research progress on the electrochemical behavior of metallic Ca and its alloys in various electrolytes, as well as the intercalation (Prussian blue analogs, vanadium oxides, etc.) and conversion (Ca-sulfur batteries, Ca-oxygen batteries) cathode materials.

Key words: multivalent batteries, calcium batteries, electrolytes, cathode materials
